Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a packaged power generation equipment capable of floating transportation or floating power generation.

Traditionally, the construction of a thermal power plant starts with civil engineering work at the power plant construction site, then constructs the foundation for the turbine generator, constructs the turbine building, constructs the boiler steel frame, raises the boiler drum, and installs each equipment. The main components were being installed in line with the progress of civil engineering and turbine building construction.

At sites with poor local installation conditions, these installation works require a long period of time and have a large impact on power plant construction prices. Furthermore, it is important to transport and bring in each element of the power plant's component equipment in accordance with the installation period, which increases transportation costs. Particularly for power plants built in underdeveloped areas, securing skilled engineers is also an issue.

The power plant components and turbine building will be installed on a floatable platform, fabricated and assembled in a factory into one huge package, and this package will be able to be submersible. A type barge is used to transport the power plant using waterways such as sea or rivers to the vicinity of the power plant construction site, tow it to a pre-prepared installation site, and place it on the ground by injecting water into the ballast tank installed on the above-mentioned ship's platform. By backfilling and connecting to electricity, water, fuel equipment, etc. outside the package, the on-site installation period can be drastically shortened, and the power generation equipment can be manufactured in the factory with sufficient quality control. A power plant system is being considered.
The package type power generation equipment will be explained below using the drawings.

Figure 1 is a partially cutaway plan view, and Figure 2 is a straight line from Figure 1.
- Cross-sectional view (side view) along ■, Figure 3 is the straight line ■ in Figure 1
It is a sectional view (front view) along -■. In the figure, reference numeral 1 denotes a ship's platform, which has a ballast tank 1' and is manufactured in a dock in a factory like a normal ship. 4.Main equipment such as transformers 5, 6, 7, etc., and their auxiliary equipment such as forced draft fan 8, chimney 9, condenser 10, circulating water pump 11, diarerator 12, compressor equipment 1
3. Water supply pump equipment 14, and hydrogen gas generator 15
, a storage battery facility 16, a control room 17, a crane and hoist facility 18, an emergency power generation facility 19, and other power plant components are mounted and configured as one huge package P. Reference numeral 20 in the figure is a turbine generator building for protecting these devices. Each of these devices constituting the power generation package is manufactured in a factory in a short period of time under strict control, and then assembled and mounted on the ship's platform 1. FIG. 4 is a diagram showing a state in which the power generation package P is transported on water. In the figure, P is the power generation package, and B is a submersible barge on which the power generation package P is mounted. Further, T is a towing vessel for towing this submersible barge B, and S is a waterway, such as the sea. In this way, the power generation package is towed close to the power plant construction site by the towing vessel T. In this way, packaged power plants can be manufactured and assembled in bulk by the manufacturer, including the power plant equipment and the building that houses them, and can be installed anywhere in the world as long as it can be transported by water. . It is also clear that the power generation package described above can be used as a mobile power station that is not fixedly installed on land, but is fixed floating on water and transmits the generated power to land for a predetermined period of time.

However, in order to construct a packaged power generation facility in a compact form, it is necessary to mount the oil-immersed transformer, which was conventionally installed outdoors, inside the package.

Conventionally, it was not possible to house and install oil-immersed transformers inside buildings due to technical issues such as effective space usage, fire prevention, soundproofing, and eliminating any repercussions in the event of a transformer accident. Answer to a question! This was because it was difficult. The present invention was made in view of the above-mentioned problems, and includes an oil-immersed transformer, which is one of the components of packaged power generation equipment, mounted in a package, thereby making effective use of space and achieving fire prevention and soundproofing effects. The object of the present invention is to obtain a packaged power generation equipment that can completely eliminate any spillover of the accident to other equipment even if oil gushes due to an accident inside the transformer.

Therefore, in the present invention, a transformer room is provided to house the oil-immersed transformer, and the transformer is installed within the transformer room. An oil barrier structure will be installed in the bottom structure of the package, and the transformer room and the bottom structure will be connected by a connecting pipe to prevent oil from leaking to other areas during oil injection. Hereinafter, the present invention will be described in the fifth section.
The embodiment shown in FIG. 6 and FIG. 6 will be described.

In the figure, 5 to 7 are transformers, 20 is a generator building,
21 is a transformer room that is a part of the generator building, 22 is a ballast tank that also serves as an oil barrier structure, 23 is an oil barrier installed in the transformer room, and 24 is a transformer room and bottom levee structure. This is a connecting pipe for connecting ballast tanks.
Normally, when a transformer, which is a component of packaged power generation equipment, is housed and installed in a packaged building, the transformer is housed in a sealed transformer room in order to maximize the effectiveness of soundproofing and fireproofing equipment. However, due to the fact that it is sealed tightly, maintenance and inspection work is much more difficult than when it is installed outdoors.

Furthermore, since a complete set of power generation equipment is installed in a limited package space, the layout becomes complicated, and depending on the layout, multiple transformers or transformers and other equipment may be installed in the same room. They are forced to live together in the same room. If an accident occurs inside the transformer under such conditions, there is a drawback that it is not possible to prevent the accident from spreading by spraying oil. or,
Even when accidents are minimized, maintenance and inspection in a limited space is inefficient, and considerable losses are incurred until the accident is recovered. Therefore, the present invention provides a transformer chamber 21 in which all the transformers 5 to 7 or a part thereof are housed in the package, and the transformer is installed in this chamber, and in preparation for an accident inside the transformer, An oil barrier 23 is installed in the transformer room 21 and the ballast tank 22 as a ship's bottom structure, and the transformer room 21 and the ballast tank 24 are connected by a connecting pipe 24, so that in the event of a transformer accident, oil can be transferred to other places. The structure is such that the oil is collected in the ballast tank 24 through the communication pipe 24 to prevent oil from flowing out. Therefore, the accident does not spread to other equipment, and accidents can be kept to a minimum. As explained above, if the present invention is used, even if an oil-immersed transformer, which is a component of packaged power generation equipment, is installed in a package, space can be used effectively, while maintaining fire prevention and soundproofing effects. This has the effect of completely eliminating any damage to other equipment even in the unlikely event that oil gushes due to an accident inside the transformer.
